WIRE-SCREEN RACK.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed April 17, 1913. Serial No. 761,772.

be employed as a support for any other ma-v Y terial or object for which it is adapted.

The primary object of our invention is to provide a rack capable of holding a plurality of rolls of wire screening in such a manner that the screening of one roll cannot come into engagement with that of any other roll and so become entangled therewith, while at the same time in such a manner that the screening may be unrolled from any desired roll without removing said roll from the rack.

A further object of our invention is the.

provision of a table over which the screening may be drawn as it is unwound from the various rolls and upon which 1t may be supported while measured and severed from the roll. And a further object of our invention is to provide means for raising and lowering the table upon the rack to bring it into position to properly receive netting p drawn from any roll of the rack. And a 35 still further object of our invention is to so arrange the table that it may be swung or folded upwardly against the front of the rack and out of the way when not in use.

With these and other objects in view, our invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of `this application.

In the drawings: Figure 1 is a perspective view of our improved rack, showing the table in operative position; Fig. 2 Lis a horizontal sectional view taken in a plane above the table, the table in this view being broken ,in iiwpefativ Positions Fie @is fd. fragmentary sectional view, showing a pawl land Vratchet mechanism by zmeans of which the locking of the table in adjusted position is accomplished; Fig. 5 is a' fragmentary perspective view of oneform of roll supportingk tray employed in our rack; Fig. 6 isa similar view of the other form of roll supporting tray. l

Corresponding and like parts are referred to lin the following description and indicated in all the views of the drawings by the same reference characters.

In the drawings, which illustrate the pre-Y ferred embodiment of our invention, 10 and 11 designate a pair of vertical frame members, kthe upper ends of which are maintained in spaced relation by a horizontal frame member 121, while 13 and 14 designate correspondingly spaced rear frame mem- Y bers, the upper ends of which are maintained in proper spaced relation by a horizontal frame member 15. The upper ends of the forward and rear frame members 10 and 13 are connected by a horizontal frame member 16, while the upper ends of the frame members 1l and 14 are connected .by asimilar horizontal frame member 17.

YBraces 18 and 19 connect and maintain in proper spaced relation the lower ends of the frame members 10-13 and 11-14 respectively, and the free ends of these braces are extended beyond said frame members and bent downwardly slightly to form supporting feet 2() which may be perforated to receive a screw or bolt by which the rack, as a whole, may be firmly secured in place. The frame members 13 and 14 are braced to the frame members 16 and 17, respectively, by diagonal braces 21, while the frame members 10 and 11 are similarly braced to the base formingbraces 18 and 19 by diagonal braces 22. A vertical frame member 23 connects the central portions of the frame members 16 and 18, while a similar frame member 24 connects thecentral portions of the frame members 17 and 19.

The above described frame may be of any desired size and proportions and constructed of any suitable'material. We prefer however, to form the frame wholly from metal and when so formed we have found that angle iron is far superior to any other material for all parts of the frame above described, ,Save the, braces, 2,1 and, 22,

The vertical frame members 10 and 11 are connected at spaced intervals by horizontal supporting bars 25, the vertical frame members 23-4 are similarly connected by spaced supporting bars 2G and the vertical frame members 13 and 14 are connected by spaced supporting bars 2T, the ends of these bars in each instance being riveted, bolted or otherwise secured to the flanges of the adjacent frame members. As will be noted by reference to Fig. 3 of the drawings, the supporting bars connecting the front frame members of the rack, that is the frame members l0 and 11. are positioned slightly lower than the corresponding supporting bars connecting the frame members 23 and 24 which are in turn, positioned somewhat lower than the bars corresponding thereto and connecting the rear frame members 13 and 14.

Each of the bars 25, together with the next adjacent bar- 26, that is that bar 26 at a level immediately above the bar 25, forms a support fora roll holding tray 2S, while the bars 26, together with their corresponding bars 27, form supports for a plurality of trays 29. Each of the trays 28 is preferably formed from a single piece of sheet metal curved transversely throughout its length to provide a trough shaped body for the reception of the roll of screening to be supported therein and having its forward edge portion bent downwardly as at 30 to hook over one of the bars Q5 and its rear edge portion bent downwardly as at 3l for similar engagement over the corresponding bar 26. Each of the trays 29 is formed in the same man` ner from a single sheet of metal which however, is considerably wider than the sheet of metal employed in forming the trays 2S and with which the trough holding body portion is formed by one side having the downward folded edge portions 32 and the former of which engages over one of the supporting hars 27, while the latter engages over the hooked edge portion 31 of the adjacent tray 28, the extended portion 34 of this downbent portion B3 being directed forwardly and downwardly to act as a guard for any roll positioned in the adjacent tray 28.

From the foregoing description of the trays and the manner of mounting the same, when taken in connection with the drawings, it will be apparent that a rollof wire netting or screening may be placed in each of the trays and that by engaging the free end of any roll` netting may be unwound from the same without removing the roll from its tray and without any danger of the netting engaging against and becoming entangled with the netting of any other roll. Any netting being removed from either of the front trays will be drawn outwardly through the front of the rack between said tray and the guard of the adjacent rear tray, while any 1,1ee,eso

netting being removed from either of the rear trays will be drawn forwardly between the guard carried by 'said tray and the bottom of the forward tray immediately above said guard. lt will therefore be clear that the guards absolutely prevent any entangling of the netting of the rolls contained in the front trays with those contained in the rear trays.

lt will of course be understood that instead of constructing the rack with two rows of trays, one positioned back of the other as shown, the rack may be constructed with one row of trays and that in this case trays of the type shown in Fig. 5 will be employed as there will be no necessity for the shields carried by the trays shown in Fig. 6. It will further be apparent that three or more rows of trays may be employed, if desired, providing the shield of each row, save the front row, be extended completely through the rack to the front to pervent the rolls of netting contained in its trays from becoming entangled with the rolls of netting contained in the other trays.

Having thus described the construction of the rack proper we will now describe the table upon which thenetting is supported while measured and cut and the manner in which it is mounted upon the rack. This table includes a frame carrying the bed of the table 36, one side of which is cutaway as at 37 to enable one to more readily reach across the table when cutting' off a piece of netting. This table is swingingly mounted at its rear end by hinge bolts 88 between hangers 39 and 40 movable vertically upon the ends of the rack. Each of these hangers is preferably formed from a piece of angle iron. the end portions of which are oppositely bent from the body portion. to space one above and one below the body portion when the hanger is in position with its end portions extending in horizontal planes. The terminal of the rear end portion of each hanger is doubled inwardly upon itself as shown at 41 to form ay housing for a roller 42 journaled upon a. bearing pin passed through said doubled portions and engaging against the outer face of the rear flange of the frame member 23 or 24, as the case may be. A Z-shaped bracket 43 is secured to the outer end portion of each hanger to receive, in connection with the hanger7 a bearing pin for a roller 44 which engages against the forward face of the frame member l0 or 1l. as the case may be. Keepers 45 and 46 carried by the intermediate portions of the hangers extend over the inner faces of the member 23 and 24 and lO-ll, respectively` to pre-` passed through the terminals of the for-l ward end portions of the hangers, receiving the weight of the table, maintain Vthe rollers in close engagement with their respective frame members. The rear end of the table frame is provided at each side with an extension or stop 47 which, when the table is lowered` to horizontal position, engage beneath the brackets 43 to prevent further downward swinging of the table.

. In order to provide means for raising and 10 lowering the table and also for holding the table in adjusted position, the frame members 16 and 17 are provided at theirforward ends with alined bearings 48 to receive a shaft 49, which may be either tubular or solid, and upon each end of which is secured a pulley 50. One end of the shaft extends through one of thepulleys 50'to receive a crank 5l by means of which the shaft and pulleys may be rotated.v A cable 20 52, preferably formed of wire, is connected by one end to the intermediate` portion of each hanger and by its other end to the adjacent pulley 50. It will therefore be apparent that rotation of the shaft 49 through turning of the crank 51 will wind or unwind the cables 52 upon the pulleys 50 to raise or lower the hangers and table carried thereby.

Keyed or bolted upon the shaft 49 between that bearing 48 and pulley 50 adjacent the crank 51, is a ratchet wheel 53 and pivoted upon the frame member 10 below the ratchet wheel, as at 54, is a pawl 55 adapted to engage the ratchet wheel to lock the shaft against counter-rotation. This pawl 55 is provided with an extension 56 projecting from the pivotal Vend of the pawl and forming a counterweight for automatically maintaining the pawl in engagement with the ratchet wheel. An arcuate plate 57 extends in spaced relation to each of the pulleys 50, these plates being secured by their ends to the frame in the manner clearly shown in Figs. 3 and 4 of the drawing and slotted for passage of the cables 52. The function of these plates is to prevent disengagement of the cables from the pulleys.

In order to facilitate the measuring and cutting of the wire netting carried by our rack, the table is preferably marked off at one side with scale divisions 58 in order that the table itself may be employed in measuring the netting. Furthermore, the table is ce' provided along its inner edge with a strip of soft metal 59 and upon this with a pair of parallel spaced-apart bars ofmetal 60, these bars being preferably spaced very close to each other. In measuring netting 60 the netting is drawn out over the table and when the proper amount has been so drawn out, the netting is laid in place over the strip and bars above described and a sharp knife drawn across the `netting between the bars which serve as guides to insure the i vention,

straightcutting of the netting. The strip of soft metal prevents undue cutting of the table by the knife.

From the foregoing description, taken in connection with the drawings, the operation 7,0 ofour improved rack will be readily understoodl and but veryslight description of the same is necessary.V Assuming that the various rolls of screening or netting have been positioned in the roll holding trays and their ends drawn to points where they may be readily reached from the front of the rack, if a salesman wishes to display any one of the nettings' contained in the rack or to cut offi a piece of any one of said nettings 8 0 he can swing the table to horizontal position as shown in Fig. 1, raise or lower it through the action of the crank 51 to a position substantiallyopposite the tray containingthe particular roll fromwhich the 8.5. nettingis to be drawn, and then. draw the netting from the roll onto the table. It will be apparent that the table will be automatically prevented from4 swinging below the horizontal position and automatically locked in the position to which it has been raised or lowered because of the engagement of the pawl 55 with the ratchet wheel. It will therefore be seen that we have provided a rack capable of holding a relatively large number of rolls of netting and having a single table which may be readily moved to bring it into position to receive netting drawn from any roll contained in the rack and which, when not in use, may be swung upwardly against the front of the rack and out ofthe way, the table, in this position, obviously, shielding the trays.

The rolls of netting are positioned inthe trays in such a manner that their free ends eXtend forwardly between the rolls and the trays and the weight of the rolls, therefore, is sufficient to hold the netting against displacement from the trays even while the same is being unwound. It is to assist in holding the netting in the trays that the rear edges of the trays are in all cases supported at a slightly greater elevation than the forward edges, the tendency upon un-y rolling netting from any roll being to cause the roll to move backward.

Although we have described the above rack as a rack for supporting rolls of wire netting or screening, it will of course be understood that it may be employed for any other purposes for which it is adapted and it will further be understood that we do not wish in any way to limit ourselves to the specific details of construction, illustrated in the drawings and described in the above specification, as various minor changes within the scope of the appended claims, may be made at any time` without in the slightest degree departing from the spirit of our in- Having thus described the invention, what is claimed as new is:

l. A rack including a frame,y trays disposed one above the other in the frame, a shaft journaledf on the top of the frame, a crank for the shaft, pulleys on the shaft, hangers movable vertically on the frame, cables trained over the pulleys and. secured to the hangers, and av table carried by said hangers and movable to points opposite the trays, said table being swingingly mounted between the hangers to fold against the frame and trays. p
